The average F of the whole PRE population (328,706 animals) has decreased from 8.45% to 7.51% in the least 20 years. The Fij was estimated for the whole PRE population, resulting in a database of 58,772,533 records containing one record for each Fij that each animal receives from a certain common ancestor (CA). A total of 10,244 CAs contributed to the Fij with an average of 5370 descendants, with each descendant having an average of 170 CAs. Over the generations, the number of CAs has increased, while the proportion of Fij by each one has decreased. In addition, the contributions of the more influential ancestors have changed. The increased census, the limited use of artificial insemination and our increased knowledge about inbreeding depression and the animals\u2019 breeding values allow breeders to select horses more for their functionality and conformation than for their pedigree reputation, which is the cause of all these changes.<\/jats:p>","DOI":"10.3390\/ani10081360","type":"journal-article","created":{"date-parts":[[2020,8,6]],"date-time":"2020-08-06T09:41:21Z","timestamp":1596706881000},"page":"1360","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Genetic Structure Analysis of the Pura Raza Espa\u00f1ol Horse Population through Partial Inbreeding Coefficient Estimation"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2618-105X","authenticated-orcid":false,"given":"Davinia I.","family":"Perdomo-Gonz\u00e1lez","sequence":"first","affiliation":[{"name":"Departamento de Ciencias Agro-forestales, ETSIA, Universidad de Sevilla, Carretera de Utrera Km 1, 41013 Sevilla, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mar\u00eda J.","family":"S\u00e1nchez-Guerrero","sequence":"additional","affiliation":[{"name":"Departamento de Ciencias Agro-forestales, ETSIA, Universidad de Sevilla, Carretera de Utrera Km 1, 41013 Sevilla, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9566-6600","authenticated-orcid":false,"given":"Antonio","family":"Molina","sequence":"additional","affiliation":[{"name":"Departamento de Gen\u00e9tica, Universidad de C\u00f3rdoba, Campus Universitario de Rabanales, Edificio Gregor J.
